Feelings are a consequence of the events of your day. Working quietly beneath the radar of rational thought, feelings can last a moment or a lifetime. Feelings represent your honest response to the events at hand. They are a gateway to understanding your character more deeply - appreciating what really matters to you and what makes you feel alive.
Here are a diversity of perspectives from the movies about feelings.

"We don't have the luxury of deciding when and where we want to care about something."

"That's how it starts, the fever, the rage, the feeling of powerlessness. It turns good men cruel."
